Friday, November 17, 2000Leonid Meteor shower Nov 17th & 18th: MODIS will remain in nominal B-side science operations, however, all calibration activities will be suspended during this time.
Maneuvers:
Wednesday, November 15, 2000The next MODIS Roll Maneuver is schedule for DOY 320 22:41:59 to 22:58:59 for a roll angle of -11.5506 degrees.
MODIS Anomalies:
No formatter anomalies have been detected since switching to B-side science operations. The MODIS IOT is continuing to monitor changes with the radiative cooler temperatures and focal plane power.
General Instrument Comments:
MODIS is in Science Mode on the B-side with the SVD and NAD open, operating with the Formatter Resolution Flight Software Patches (FRFSP). No new events have been witnessed by the FRFSP since the B-Side Transition on DOY 304.
MODIS Telemetry Trends:
The Radiative Cooler intermediate stage temperature has slowly been increasing since approximately day 240. During this time the LWIR focal plane heater margin has been decreasing. The IOT is continuing to trend these telemetry mnemonics.
Non-MODIS Significant Events:
None.
